One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

The completed sequencing of entire bacterial genomes and recent advances in genomics has allowed the identification of many genes. While several genes have been characterized, the function of the ...

COLUMBUS, Ohio – Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help ...

Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns.
